Do I need to use my Dexcom receiver for my Dexcom Continuous Glucose Monitoring (CGM) System to work?

You have the flexibility to use only the Dexcom G6 app, only the Dexcom receiver, or both at the same time, depending on your diabetes management preferences.
For Medicare customers: Medicare does not cover Dexcom G6 CGM supplies that are used only with a smartphone or other mobile device. Here are some examples of how a Medicare patient may use a smart device with their Dexcom receiver:
  • A patient uses both a receiver and a smartphone throughout the day
  • A patient uses a receiver some days of the week and their smartphone other days of the week
CMS Policy
Coverage of CGM system supplies and accessories are available for those therapeutic CGM systems where the beneficiary uses a receiver classified as DME to display glucose data. There is no Medicare benefit for supplies used with equipment that is not classified as DME. However, Medicare coverage is available for the CGM system supplies and accessories if a non-DME device (smartphone, tablet, etc.) is used in conjunction with the durable CGM receiver. Coverage of CGM system supplies and accessories are available for those therapeutic CGM systems where the beneficiary uses a receiver classified as DME to display glucose data. If a beneficiary intends to never use the receiver as the display device, the supplies and accessories are not covered by Medicare.
Patients should reach out to 1-800-MEDICARE with any questions about the Medicare coverage requirements for Dexcom CGM.
